what is the answer to the volleyball team at blue point high school has saved $680 and the team plans to spend no more then that
zloy xaker [14]

Answer:

6 x + 23 y  < $ 680  represents the combinations of x balls and y nets that can be purchased.

Step-by-step explanation:

The number of balls than can be purchased  = x

The number of nets than can be purchased  = y

Total savings  = $ 680

Now, the cost of 1 ball =$6

So, the cost of x balls = x ( cost of 1 ball) = x ( $6)  = 6 x

Also, the cost of 1 net =$23

So, the cost of y nets = y ( cost of 1 net = y ( $23)  = 23 y

So, the total amount spent on x balls  and y nets

= Amount spent on x balls + Amount on y nets

=  6 x + 23 y

Also, the saved amount is $680

⇒<u> 6 x + 23 y  < $ 680</u>

Hence, 6 x + 23 y  < $ 680  represents the combinations of x balls and y nets that can be purchased.
